UNITED STATES CHESTER J. MOC R-E, OF ERIE, PENNSYLVANIA.

ADJUSTABLE JAVLT WRENCH.

Application filed January '7, 1924.

Pennsylvania, have invented certain new and useful l inprovementsin-Adjustable J aw Wrenches, of which the following is a specification.

This invention relates to certain new and useful improvements inadjustable jaw wrenches and has particular reference to a wrench of thischaracter so constructed and having a handle so formed as to permitready turning of nuts located in inaccessible places and through whichbolts may extend for such an undue or unusual distance as to preventmanipulation or turning of the nut through the medium of conventionalsocket wrenches.

An object of the invention is toprovide a wrench of the above kind whichis simple and durable in construction so as to be man-- uiactured andmarketed at a relatively low cost and which may be easily and readilymanipulated to overcome the above noted objection to socket wrenches.

Still another object of the invention is to provide an adjustable wrenchincluding a wrench head having a rigid and an adjustable sliding jaw atone end and provided with a socket at its other end for removablereception of socket wrench handles of angular form, whereby the wrenchmay be e1nployed for turning nuts located in inaccessible places or forturning nuts thru which the bolts extend for an unusual distance.

Other objects will appear as the nature of the invention is betterunderstood and the same consist in the novel form, combination, andarrangement of parts hereinafter more fully described, shown in theaccompanying drawing and claimed.

In the drawing, wherein like reference characters indicate correspondingparts throughout the several views:

Figure 1 is a top plan view of a wrench head constructed in accordancewith the present invention.

Fig. 2 is a view partly in side elevation and partly in section of thewrench head shown in Fig. 1, with a socket wrench handle of special formoperatively engaged therewith.

Fig. 2 is a view partly in section and partly in side elevation of awrench and han- Serial No. 684,811.

dle somewhat similar to that shown in Fig. 2 but wherein the handle andwrench head are integral.

Fig. 3 is a view similar to Fig. l, but partly in section, illustratinga modified r'orni of wrench head constructed in accordance with thepresent invention.

Fig. d is a view similar to Fig. 2 showing the wrench head illustratedin Fig. 3 with a special form Of handle applied thereto; and

Figure et is a view somewhat similar to Fig. 4 illustrating a wrenchhead provided with an integral handle similar to the handle illustratedin Fig. 4.

liieiterring more in detail to the drawings, the present inventionembodies a wrench head a; formed at one end and adjacent one side withan integral or rigid jaw 6, an adjustable slidable jaw 7 being carriedat this end of the wrench head 5 EH01" movement transversely of thelatter toward and away l L'OHI the rigid j aw if and any suitable meanssuch as a nut 8 confined in an opening 9 of the aw head 5 and threadedupon a threaded stem. 10 rigid with the adjustable jaw 7 being providedfor adjusting the latter jaw toward and away "from the rigid jaw 6. Thewrench also embodies handle member projecting from the opposite end ofthe wrench head 5 and rigidly associated with the latter, which handleembooies parallel oppositely directed end portions 11 and 12 that areoffset relative to each other and connected by a lateral intermediateportion 13. As shown in Figs. 2 and 2 the intermediate portion 13 may beextended at right angles to the end portions 11 and 12 of the handle soas to substantially form a crank for causing rotation oi the nut heldbetween the jaws 6 and T of the wrench head, which jaws are parallelwith the intermediate portion 13 or" the handle. However, as shown inFigs. 4 and the intermediate portion 13 of the handle may be disposed atan obtuse angle to the end portions 11 and 12 of the handle so that theouter end portion or hand-grip portion 12 of the handle is locatedparallel with the plane of the wrench head but in a plane spaced fromthat of the wrench head and the inner end 01" the handle so that turningof nuts located in inaccessible places may be effected. Also, in theforms of the invention shown in Figs. 4 and 4 the end portions of thehandle are parallel with the plane of the wrench head and the handleprojects rearwardly from the rear edge of the wrench head.

In the forms of the invention shown in Figures 1 and 2, the rear end ofthe wrench head 5 is provided with a central transverse socket oropening it of polygonal form for snug reception of the inner end of thewrench handle so that wrench handles of various forms may beinterchangeably employed, while in the form of the invention shown inFigure 2 the handle is formed integral with the wrench head and extendslaterally from the latter centrally of its rear end portion.

In the form of the invention shown in Figures 3 and 4, the wrench headis pro vided with one or more substantially longitudinally extendingsockets 14; that open through the rear end of the wrench head and areadapted for snug removable reception of the inner end of a wrench handleas shown in Fig. 4, so thatthe inner id portion of the vided in theinner end of the wrench head as shown in Fig. 3, the handle may beassociated with the wrench head so as to be disposed to extend in eitherdirection at an angle to the longitudinal axis of the wrench head,thereby permitting most effective op eration under particularcircnmstam-es or conditions.

From the foregoing description, it is be lieved that the constructionand operation as well as the advantages of the present invention will bereadily understood and appreciated by those skilled in the art.

\Vhat I claim as new is:

In an adjustable jaw wrench of the character described, a flat wrenchhead having a rigid jaw upon its outer end and adjacent one side of thesame, and provided with a transversely slidable adjustable aw upon itsouter end in coooperative; relation to the rigid jaw, means for manuallyadjusting said adjustable slidable aw, a handle adapted for rigidassociation and attaclnncnt to the wrench head at the rear end of thelatter, said handle comprising parallel end portions connected by alaterally extending intermediate portion, said wrench head having a pairof sockets in the inner end thereof, said sockets extendingsubstantially longitudinally of the wrench head but at rearwardlydiverging relation to each other and adapted for selective snugreception of the inner end of the handle.

In testimony whereof I aflix my signature.
